Solving Nonlinear Systems ------------------------- For linear systems, see :meth:`Matrix.solv`. ---- .. function:: prmat Prints the form of the matrix defined by :ref:`eqn ` statements. Each nonzero element is printed as an "*". ---- .. function:: solve Does one iteration of the non-linear system defined by :ref:`eqn ` statements. Returns the linear norm of the difference between left and right hand sides plus the change in the dependent variables. ---- .. function:: eqinit Throws away previous dependent variable and equation specifications from :ref:`eqn ` statements.
